Pre-Alarm: When the alarm detects over 50ppm CO the red light flashes every 2 seconds. This helps

locate CO leaks as the unit gives a visable indication straight away (the horn will not sound unless the

50ppm of CO remains for at least 90 mins). Note the Pre-Alarm signal may be triggered by CO coming

for example, from cooking with gas, from car engines or from nearby barbecues. This is usually not a

concern unless the Pre-Alarm signal persists until the alarm sounds and the CO source is unknown.

Note: The CO Alarm may pre-alarm if cigarette smoke is blown into it, or aerosols are released nearby.

2.4 CO ALARM MEMORY

When the Test button is pressed the horn will sound, and the alarm red light will only flash if the unit has

previously detected CO and been in alarm. The flash rate indicates the level of CO detected as below:-

- Alarm Red light is Off – No CO detected since reset or power up.

- Alarm Red light flashes 2 times (in 2 seconds) every 40 seconds - 50 ppm CO detected for

approximately 90 minutes since reset or power-up.

- Alarm Red light flashes 4 times (in 2 seconds) every 40 seconds - 100 ppm CO detected for

approximately 40 minutes since reset or power-up.

- Alarm Red light flashes 8 times (in 2 seconds) every 40 seconds - 300 ppm CO detected for

approximately 3 minutes.

Reset Memory by holding down the Test button for over 20 seconds until the alarm red light stops

flashing. Cover the horn with a cloth to muffle the alarm during this time. (Note any other RadioLINK

device will also alarm during this period).

Please note that the memory will also be reset when the unit is removed from the mounting plate.
